A voltage source sends a current of 2 A to a resistor of 40 Ω connected across it for 5 minutes. Calculate the electrical energy supplied by the…

Given \(\displaystyle \mathrm{I}=2 \mathrm{~A}, \mathrm{R}=40 \Omega, \mathrm{t}=5\) minutes \(\displaystyle =300 \mathrm{~s}\) Electrical energy \(\displaystyle =\mathrm{I}^{2} \mathrm{Rt}\) \[\begin{gathered} =(2 \mathrm{~A})^{2} \times 40 \Omega \times 300 \mathrm{~s} \\ =48000 \mathrm{~J} \end{gathered} \]
